I see and read most of the new patents, I get the feeling that Canon may come out with minor modifications to the lenses that will bring some improvements --- better coatings, faster AF, etc. But also improved manufacturing processes (read lower cost to manufacture, assemble, and test). And then, a higher selling price.

A big relevation is going to hit camera owners when they start using the new focusing tools that FoCal Pro offers, and I expect others to do this too. Some lenses focus very erratically, we have known this, but could not quantitfy it. Others are amazingly good. Now that a careful test can measure the focus accuracy and repeatability with a given camera body, we will soon see some of the popular lens testers start to publish data. It does require a test of several lenses from different manufacturing batches to really see if there is a common issue, but users may soon be able to submit them and a overall pictire of which lenses AF consistently and accurately will start to appear.

When I compared the same batch of primes and zooms on both my 5DMK II and my 7D, I found that they behaved almost identically on the two different bodies.

Improving those lenses would be good, some may require some "build" improvements, especially the 50 f/1.8 and hopefully get better AF systems.

Also, making those lenses EF-S would be a stupid / very negative move as many people with EF mount only cameras use these lenses; say 50 1.4, 1.8, 85 1.8... and i see many advanced/pros using the 50 1.4 for example. It would also mean a loss for Canon because they would be losing the sales of these lenses from all the people who own EF mount cameras.

There are a range of camera bodies to fit users with different needs and budgets. These lenses were all designed in an era when that entire range of cameras was full frame, i.e. film. Today, FF cameras from Canon cost $2K and up, and the quality (and thus, consumer popularity) of zoom lenses is an order of magnitude higher than what it was when these EF primes came out. I doubt we'll see the cheaper EF primes updated as anything other than EF-S, and very few of those, probably only one 'normal' prime, maybe one wide prime. They might update the 28/1.8, 50/1.4, and 85/1.8 as EF, as Mt. Spokane suggested - newer coatings, better AF (for the 50/1.4), and most importantly, cheaper manufacturing. Of course, those new lenses would be more expensive, meaning more profit for Canon. But, I expect their priority going forward will be on L series lenses and EF-S lenses, as it has been for the past few years.

i cant see why they would change them to ef-s it cuts down potential sales but EF mounts can be used on both and if you want an equivalent EF-s focal length then do the math and get the corresponding lens, EF-S only primes dont make any sense i'm not sure why people keep banging on about it. perhaps a dedicated EF-S ultra wide prime to cover the end that gets lost in translation makes sense but why bother with an ef-s 50 or 85 etc

How do we know that Canon intend to support APS-C in prosumer bodies in the long term when the industry trend is to have APS-C in P&S and other entry level consumer cameras? If there is no long term future for high end APS-C the Canon are unlikely to release high end lens especially for them - perhaps that is why they haven't already .....

Agreed

Canon does have a lot of APS-C bodies in circulation, and sales is going strong. so there is momentum. However, at some point, that will change, and some new standard will phase in.

The only question is when. 5 - 10 -50 years? I have no guess.

I have no reasonable expectation that EF lenses will be in production in the future either. Things do change. That doesn't stop me from buying them, because I use them now.

Canon is a huge company, very conservative and slow to change, but when they finally do, they do it big, and tend to be successful more than they are wrong.

I would agree that there is very little sense in making a wide variety of EF-S prime lenses, other than maybe a 30mm ~f/1.8 which would serve as a good standard focal length lens on APS-C cameras (maybe an 17-18mm EF-S would be popular). Otherwise, seems to me most APS-C camera users will be zoom users. It's the FF users who really get the most benefit from primes, and therefore would probably be the most likely to invest in primes. If Canon focused on making just EF-S prime lenses, it would probably not be nearly as profitable as making EF primes.

From the various rumors we've been hearing over the last few months, I'm getting the feeling that Canon is about to revamp their entire line of EF primes.

Possibly all at once, even.

I just wonder if they'll turn them all into EF-S lenses, and keep EF mainly for L and specialty lenses from here on out?

I agree to an extent, but not necessarily ALL of those.. The 50mm f/1.4 is a 20+ year old design and so is the 50mm f/1.8, and its such a standard FL I'd be very surprised if we didn't see a Mark II soon. I don't think they'll update all of the 20mm range lenses you mentioned, but I think the rest are somewhat possible.

People seem to be buying primes more and more, and these lenses L-counterparts are much more expensive, not updating them for the new breed of DSLR shooters would be foolish.

The equivalent of 135mm on FF would be 85mm on APS-C, and there's a market for EF 85mm.The equivalent of 85mm on FF would be 50mm on APS-C, and there's a market for EF 50mm.The equivalent of 50mm on FF would be 32mm on APS-C, and photographers could go for 35mm (55mm prime was often sold as prime normal) or 28mm (~1mm longer than the diagonal for Canon's APS-C), and there's a market for both.The equivalent of 35mm on FF would be 22mm on APS-C, and Canon already makes an EF 20mm.

Wider than that, Canon has no cheap primes, and I gather a crop sensor makes it easer to produce wide primes.

Until Canon has a full frame body that is under $2000 at release, there will still be a market for reasonable priced prime lenses. There are people stating that full frame users are those who derive the greatest benefit from fast primes, I beg to differ; if you are struggling to achieve shallow depth of field due to the smaller sensor on APS-C cameras then fast primes make even more sense: look at their popularity on the 'mirrorless' cameras.

That said, I don't think that straight replacements for the old EF primes is the way to go. An ideal lineup would be a fast (i.e. f/2 or faster) 15mm, 22mm and 30mm EF-S in the $600-$700 price bracket (like the new Fuji XF lenses). Before everyone moans that they should be EF mount, there are design advantages that come with the reduced coverage and back focus distance of EF-S when it comes to the wide-normal range.
